Right-handed starter Jason Marquis allowed one run on three hits over 7 2/3 innings and Alexi Amarista, Nick Hundley and Yonder Alonso combined to drive in eight runs Tuesday night as the Padres defeated the Los Angeles Dodgers 9-2 before 35,898 at Dodger Stadium. Starting with Monday night’s 6-3 win, the Padres have won back-to-back games for the first time this season while claiming their first series win of the campaign. They have also won six of their last seven games at Dodger Stadium. The Padres scored four runs in the top of the first and never looked back, extending their lead to 5-0 and 8-1. The Padres have hit .316 and averaged 5.8 runs a game in five games against the Dodgers this season while hitting only .210 and averaging 2.78 runs in their other nine games. Marquis became the first Padres starter to pitch beyond the sixth inning this season, giving the bullpen a much-needed break. He retired the Dodgers in order five times while facing only five hitters over the minimum. He retired 12 straight Dodgers from the end of the fourth through two out in the eighth. "That was a good all-around game for us," said Padres manager Bud Black. "The last two days are a good sign. "We had good at-bats all night, hitting strikes and taking balls. We put it all together. Hitting. Defense. And Marquis got better as the game progressed. His fastball command was off early. As we moved to the fourth, fifth and sixth his slider improved and his changeup got them off the fastball." Marquis was relieved by Andrew Cashner after Carl Crawford doubled with two out in the eighth. The outing was the longest by a Padre since Clayton Richard went eight innings last Aug. 25. Marquis threw 107 pitches with 63 going for strikes. And he was ready to keep going. "My job and mindset every time out there is to get quick outs and go deep into the game," said Marquis. "Once we scored those runs early, my job is to minimize the damage and keep going."
